FeaturesExternal settings allow you to easily select the settings that best fit your dog's temperament. Small, lightweight, waterproof collar is perfect for dogs of any size. Activated only by vibrations of the dog?s vocal chords along with adjustable bark detection sensitivity and an automatic safety shut-off feature make this collar safe and reliable. 4 operating modes - Warning beep sound only; Warning beep plus light stimulation (for sensitive dogs); Warning beep plus progressive stimulation; Warning beep plus strong stimulation (for stubborn dogs). At the first bark, a warning beep is emitted. If another bark is detected within 30 seconds, a warning beep and a static stimulation are emitted (light, progressive, or strong stimulation determined by the operating mode that you select). If at any point, your dog stops barking, then next bark will start the operating cycle from the beginning (beep sound only). You may also eliminate static stimulation completely by selecting the ""beep sound only"" operating mode. User-replaceable battery (included) lasts approximately 3 months with normal use.
